  • Publication number: 20150059316
    Abstract: A method for improving fuel efficiency of a vehicle and an exclusive energy saving and emission reduction device thereof are provided. The key points of the technical solutions are as follows. An exhaust separation device is installed in a crankcase of an engine. An oil-gas separation technology is adopted to manufacture an oil-gas separator and a diffusion vortex chamber. According to an aerodynamic principle, the separation degree of the exhaust is improved through compression and high speed vortex in the energy saving device, in such a manner that engine oil vapor in the exhaust is separated from combustible mixed gases, and then sent to the engine via an air intake throttle. The present invention enables complete combustion of the fuel, so as to achieve effects of oil-saving and emission-reducing.

    Abstract: A cyclonic dust collector arrangement employs a cyclone that has a conic body formed of a conic wall. An upper divider plate closes off the upper end of the conic body, with a vortex tube descending from a central passage in the divider plate. The conic body has a narrow nose at a lower end so that the upper divider plate and the lower nose define a cyclonic chamber within the conic body. The inlet conduit penetrates the conic wall below the divider plate. The fan chamber of the separator is mounted above the divider plate, and serves to induce air flow from the inlet conduit into the cyclonic chamber, and through said vortex tube into the fan chamber. The air is discharged through a final filter. This construction has reduced manufacture costs and improved dust separation.

  • Patent number: 7452395
    Abstract: An air filter has an inner filtering body within an outer filtering body. The air filter is configured to fit inside a scoop and adjacent to the inlet opening of the scoop. By placing the air filter adjacent to the inlet opening of the scoop, the size of the air filter may be increased as compared to a traditional air filter which fits within the neck area of the scoop. As such, the surface area of the air filter may be increased to provide more air to an air intake system such as a carburetor, fuel injectors, throttle body, or the like, as compared the traditional air filter. The inner filtering body may be recessed inside or protrude from the outer filtering body. The inner filtering body may be coupled to the outer filtering body along the base of the air filter. The inner filtering body increases the surface area of the air filter so that more air may be provided to the air intake system of a vehicle.

  • Patent number: 6325834
    Abstract: A filter assembly useful in collecting the particulate matter from a diesel engine onto surfaces on which the combustion vapors are condensed, and thereafter exposing the exhaust stream to catalytic reaction, is defined by a split cavity in which a row of kinematic filter discs is received. The filter discs are stacked in the assembly in a progressively finer opening size, each filter disc making an intimate contact with the assembly housing for cooling. In this manner condensation onto the discs is promoted to provide a liquid bed on which the particulate matter is trapped. The exhaust flow then passes through a coiled, corrugated catalyst surface for further reaction. A set of spring loaded bypass conduits is provided to allow diesel operation at such times when the filter plates and the catalytic coiled surface are clogged. The filter plates and the coiled catalyst strip can then be periodically removed and cleaned, for continued operation.

  • Publication number: 20010003892
    Abstract: The present invention has an object to improve the efficiency of collection of solidification constituents and solids in exhaust gas and to prevent early blockage of the filter without damaging the vacuum pump. In an exhaust path 48a, a vacuum pump and exhaust gas filtration device are provided. This exhaust gas filtration device is constituted by a trap device, pre-filter and filter. The pre-filter reduces the exhaust gas flow rate flowing through the interior of the exhaust path by controlling the exhaust gas flow path in the vessel. The aforesaid exhaust path is constituted by connecting this vacuum pump, trap device, pre-filter and filter which are arranged in this order from the side of airtight vessel and connected through piping if required.

  • Patent number: 5961931
    Abstract: A particulate trap for use with a diesel engine is high in particulate trapping capacity and regenerating capacity and low in pressure drop, and yet is compact and inexpensive. This trap has a filter element made up of a plurality of tapered filter members formed from a fabric of heat-resistant metal fibers. The filter members have different diameters from each other and are nested concentrically one inside the other so that the adjacent filter members are positioned inversely. Each filter member is connected at its large-diameter end to the small-diameter end of the immediately outer filter member to alternately close the exhaust inlet and outlet ends of the gaps between the adjacent filter members. The filter element thus formed is mounted in a metal case provided in an exhaust line and used as a particulate trap. With this arrangement, it is possible to increase the particulate trapping area of the filter and the exhaust inlet openings without increasing the size of the entire trap.

  • Patent number: 5846271
    Abstract: A filter for removing contaminants from compressed gas is disclosed. The filter features an inverse flow regime wherein gas entering the filter first flows downwardly and then reverses direction before encountering any filter media. The filter has a connection head with a gas inlet, a gas outlet and oppositely disposed openings separated by a central partition. The openings are sealingly enclosed by elongated tubular housings which releasably attach to the head. The gas inlet communicates with one side of the partition and the outlet communicates with the opposite side. A plurality of individual filter elements are arranged on either side of the partition and filter out aerosol, vapor and particulate contaminants from the compressed gas. The filter elements are releasably mounted to the central partition and can be removed and replaced independently of one another.
